Background: Since nursing performance is related to the organizational performance of hospitals, this study was attempted to determine the effects of general characteristics, clinical nursing character, and self-efficacy of nurses working in hospitals on nursing performance. Methods: The subjects were 150 nurses working in 3 general hospitals. Data collected through self-report questionnaires from January 4 to 18, 2021, were used. Data were analyzed using SPSS 23.0, and hierarchical regression analysis was performed to identify factors affecting nursing performance. Results: In the final model, the experience of the nurse’s current unit, clinical nursing character, and self-efficacy were found to be influencing factors on nursing performance. The explanatory power of the whole model was 53.6%. Conclusion Hospital administrators should carefully consider changing departments so that nurses can gain sufficient experience in the unit. In addition, it is necessary to develop and apply a program to strengthen clinical nursing character and enhance self-efficacy.

Gastric cancer is one of the most common cancers in Korea and the world. Since 2004, this is the 4th gastric cancer guideline published in Korea which is the revised version of previous evidence-based approach in 2018. Current guideline is a collaborative work of the interdisciplinary working group including experts in the field of gastric surgery, gastroenterology, endoscopy, medical oncology, abdominal radiology, pathology, nuclear medicine, radiation oncology and guideline development methodology. Total of 33 key questions were updated or proposed after a collaborative review by the working group and 40 statements were developed according to the systematic review using the MEDLINE, Embase, Cochrane Library and KoreaMed database. The level of evidence and the grading of recommendations were categorized according to the Grading of Recommendations, Assessment, Development and Evaluation proposition. Evidence level, benefit, harm, and clinical applicability was considered as the significant factors for recommendation. The working group reviewed recommendations and discussed for consensus. In the earlier part, general consideration discusses screening, diagnosis and staging of endoscopy, pathology, radiology, and nuclear medicine. Flowchart is depicted with statements which is supported by meta-analysis and references. Since clinical trial and systematic review was not suitable for postoperative oncologic and nutritional follow-up, working group agreed to conduct a nationwide survey investigating the clinical practice of all tertiary or general hospitals in Korea. The purpose of this survey was to provide baseline information on follow up. Herein we present a multidisciplinary-evidence based gastric cancer guideline.
